What is a nanojoule per second (nJ/s)?

It is a unit of power defined as one nanojoule of energy transferred each second, equivalent to one nanowatt.

Why would I convert nJ/s to femtowatt?

Converting to femtowatt allows you to express very small power levels with greater precision, useful for analyzing ultra-low-power devices and sensitive measurement systems.

Can I use this converter for instantaneous pulse power?

No, this conversion is suited for continuous or average power measurements, not for instantaneous pulses.
